Application filed May 21, 1912. Serial No. 698,768.

To all whom it may concern:

Be it known that I, J OHN MAncHE LYTLE, of the city of Baltimore andState of Maryland, have invented a new and useful Improvement inSwitch-Operating Devices, of which the following is a specification.

My invention relates to improvements in switch operating devices, and itconsists in the construction, combination, and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawing, wherein l i gure 1 is a top plan vlew of theswitch operating device constructed in accordance With my invention,Fig. 2

is a transverse sectional view taken on the vertical plane indicated byline 22 of Fig. l and looking in the direction of the arrow, and Fig. 3is a longitudinal sectional view taken on the vertical plane indicatedby the line 33 of Fig. 2 and looking in the direction of the arrow.

Referring to the drawings by reference letters, G designates the ties, Fthe rails, and F the point of a railway switch of the usualconstruction.

My switch operating device comprises a bar E, which is mounted upon oneof the ties G for a sliding movement transversely of the switch. The barE is pivotally secured to the point F as at E so that one movement ofthe bar will open the point and another movement close the point. Thebar E is adapted to be operated by a pair of levers. Each levercomprises end pieces A. which are transversely disposed and which arepivotally mounted upon the longitudinally disposed rods E and thelongitudinally disposed bars B which connect the end pieces A. Thelevers are pivotally connected to the bar E as at B. This pivotalconnection is such that when one of the levers is depressed the point Fis closed and the other lever elevated, and when the other lever isGepies of this patent may be obtained for depressed the point F isopened and the first lever elevated. The levers may be operated so as toopen or close the point F from the car by any instrument of a wellknownor appropriate construction, it only being necessary to exert a downwardpressure through the medium of the instrument on one of the bars B ofthe lever to be operated. The rods E are secured in a pair of ties G andare held in place by the nuts (I.

The switch operating device is protected by a plate T which is providedwith a pair of elongated and longitudinally extending slots T, saidslots permitting access to the bar B of each of the levers.

It should be apparent from the above description taken in connectionwith the accon'ipanying drawings, that I provide a switch operatingdevice which is simple, durable, and eflicient, and which may be used inconnection with any switch structure of well-known form, and which maybe installed and maintained at a comparatively low cost.

Having thus described my invention what I claim and desire to secure byLetters-Pat ent is:

in combination with a switch point, a slidably mounted bar pivotallyconnected to the point, said bar being disposed transversely of therailway, a pair of rods disposed longitudinally of the railway and secured to the ties, a pair of levers pivotally mounted upon the rods andpivotally connected to the bar, each of said levers coinprisingtransversely disposed end pieces and longitudinally disposed barsconnecting the end pieces, and a slotted plate disposed aboi'e the bars,rods, and levers.
